Alone confesses to Pandora that he was never possessed by Hades and that he truly believes in death as the ultimate salvation, hence he inflicts it on those he holds dear, to spare them the suffering of pain, wars and poverty, and to achieve such goals, he will use all the power of the god of the Underworld.
The Cerberus, Sagitta and Auriga Silver Saints died from the previous encounter with unknown Specters in Italy, along with Canis Major and Musca, but these three were later resurrected and turned evil by Hades, then killed by Aries Shion and Libra Dohko.
Only their constellations were revealed in the booklet included in the season 2 DVDs: Delphinus (いるか座, Iruka-za), Indus (インディアン座, Indian-za), Tucana (きょしちょう座, Kyoshichō-za), Corona Borealis (かんむり座, Kanmuri-za), Volans (とびうお座, Tobiuo-za), Eridanus (エリダヌス座, Eridanusu-za), Boötes (うしかい座, Ushikai-za), Lepus (うさぎ座, Usagi-za), Cassiopeia (カシオペア座, Kashiopea-za) and Camelopardalis (きりん座, Kirin-za).
It is later revealed that it was Hasgard who summoned Leo Ilias back to Sanctuary, ten years before the events depicted in The Lost Canvas, helping him to protect a village from Specters, and engaging Harpy Valentine in combat.
It was revealed that Defteros was manipulated in order to assassinate the Pope by his older brother, Aspros, with the attack Demon Emperor's Delusional Fist, a technique that grants the user complete control the target until the victim has witness the death of someone.
At the end of the fight, Leo simply fulminates Violate with his Lightning Plasma (ライトニングプラズマ, Raitoningu Purazuma), with it, Regulus launches multiple punches that travel at the speed of light, similar to Tenma's Pegasus Meteor Fist.
By order of the Pope, Asmita faced Defteros instead, performing his Dharmacakra Mudra (転法輪印, Tenpōrin'in) allowing the younger Gemini to dissipate his doubts and see his true identity, thus helping him free himself from his brother's control.
He then grabs the Specter from behind and performs his final technique, Lushan's Enraged Dragon Force (廬山亢龍覇, Rozan Kōryūha), an explosion of Cosmo that sends both the user and the victim flying upwards at high speed, to be burnt by atmospheric friction.
Having survived the Holy War, Dohko returns to Sanctuary, where he talks to his friend Shion about the events they witnessed, and parts to his homeland Lushan in China, upon arriving, he starts fulfilling the duty entrusted to him by Athena in the centuries to come, knowing in his heart that a new generation of Saints will fight to protect peace on Earth, in the future.
This enables him to assist his fellow Saints against the dream god, shooting his golden arrow from the Pope's temple in the Sanctuary, which is intercepted in midair and cut in four by El Cid, and then pierces the four weak spots of Oneiros, thus rendering him all but vulnerable.
Years later, bearing a grudge against his brother for his execution, Aspros tries unsuccessfully to kill his twin during their encounter in the Mars Temple, with their signature and most destructive technique: Galaxian Explosion (ギャラクシアンエクスプロージョン, Gyarakushian Ekusupurōjon), a massive burst of Cosmo that easily vaporizes opponents, said to be capable of smashing stars.
Ten years before the events in Lost Canvas, Ilias encounters Wyvern in a forest, along with Harpy Valentine, Frog Zelos and a small group of Skeleton soldiers, on a mission to destroy a local village.
She last appeared mobilizing Hades' army, after the defeat of Bennu Kagaho, later, she is enraged by Harpy Valentine's defiance, and aiming to break his will by means of torture, she performs her Noble Venom (ノーブルベノム, Nōburu Benomu) technique on him, which induces excruciating pain.
While indifferent to his brother's and sons' deaths, he further convinced Alone to embrace the darkness of Hades' essence using the Eternal Drowsiness (エターナル・ドラウジネス, Etānaru Doraujinesu) to put Alone in a deep state of sleepness, and then stood up against the invading Saints, defeating easily (albeit off-panels) Shion and Yuzuriha, and then engaging Hakurei.
With his signature technique, Cosmic Marionettion (コズミックマリオネーション, Kozumikku Marionēshon), (hence his title as "the Puppeteer") he creates invisible strings made purely out of Cosmo, with which he grabs his opponents' body, bending and twisting it as he wishes, in a grotesque and gruesome display of sadism.
Much like the original manga, Rhadamanthys, during his 18th century incarnation, is portrayed as quite a monster of a man, wielding enough power to withstand, completely unscratched, two shots from Aquarius Degel's Aurora Execution (notable for being the strongest ice technique of the entire series).
He also exhibits Galactica Death Bring (ギャラクティカデスブリング, Gyarakutika Desu Buringu), a technique that relies on immobilizing and burning the opponent's central nervous system from the inside out by channeling his Cosmo intensely through the eyes of the mask headpiece of the Garuda Surplice.
The Bennu Specter last appeared preparing to prevent Athena and her Saints trespassing the Third Demon Temple: Terra (第3 魔宮 地球, Dai san Makyū Tera), which was presented by an Ankh of black fire, in his words, the grave of his human feelings.
Heavenly Wounded Star, Mandrake Fyodor (天傷星マンドレイクのヒョードル, Tenshōsei Mandoreiku no Hyōdoru) is an extremely sadistic Specter, who has his own torture chamber in the depths of Yomotsu Hirasaka (黄泉比良坂), the Hill to the Land of Spirits.
Soon after, she was sent flying by Aiacos' Garuda Flap, withstanding its force and using it as a means to assault the Saints, freezing most of them with her mere presence, where she presented her first technique the Brutal Real (ブルータルリアル, Burūtaru Riaru), a titanic stomp which destroys completely the ground below Violate.
Earthly Beast Star, Cait Sith Cheshire (地獣星ケット・シーのチェシャ, Chijūsei Ketto Shī no Chesha) is somewhat of a comic relief character, acting more like a servant than a combatant, as he's seen riding Pandora's carriage and guiding the Specter that invaded Jamir.
Heavenly Standing Star, Dryad Luco (天立星ドリュアスのルコ, Tenritsusei Doryuasu no Ruko) is a Specter that was first introduced in the limited The Lost Canvas CD Drama, with his background further explored in the Anecdotes: Chapter Pisces short story.
Later on, the boy Pefko reveals to Albafica the true reason behind his trek to Sanctuary: Luco is no longer the kind master he knew and is secretly concocting herb brews from the Underworld that transform people into servants of Hades.
In Chapter: Pisces, Luco is shown to have control over nature ("trees, herbs and flowers", in the Specter's words), claiming that everything is part of him as a Dryad, and he is able to take over Albafica's roses, drastically enlarge their thorns and manipulate them against the Gold Saint with his technique Curse of Lily (カース・オブ・リリイ, Kāsu obu Ririi).
Later he was resurrected by Hades Heavenly Ugly Star, Deadly Beetle Stand (天醜星デッドリービートルのスタンド, Tenshūsei Deddorī Bītoru no Sutando) is probably the biggest Specter, a towering giant twice the size of Unicorn Yato, he fought him briefly inside Yomotsu Hirasaka, but was unable to defeat him when the Saint was called back into the world of the living.
Determined to never forsake his loyalty to his lord, and to punish Pandora for her slandering of the Wyvern Specter, Valentine retaliates with his Sweet Chocolate (スウィートショコラーテ, Suwīto Shokorāte) technique, listed in the Saint Seiya Encyclopedia, but never revealed by Masami Kurumada, which summons the spirits of the harpies, to absorb the lifeforce of the victim.
Heavenly Devil Star, Alraune Quinn (天魔星アルラウネのクィーン, Tenmasei Aruraune no Kwīn) is one of the most powerful soldiers of Hades' army, responding directly only to Wyvern Rhadamanthys, and close comrade-in-arms of Minotauros Gordon.
After killing his partner Minotauros Gordon by means of kaishakunin assisted suicide, Quinn attacks Dohko with his deadly Blood Flower Scissors (ブラッドフラウアシザーズ, Buraddo Furaua Shizāzu), a razor-sharp burst of Cosmo shaped as a Guillotine, severely injuring the Saint.
The Balron Specter tries to send Athena and her Saints to hell by destroying the floor beneath their feet with a powerful blast, but he is stopped by Shion's Crystal Wall, shaped as a barrier and a bridge, granting his comrades the opportunity to trespass the Venus Temple and proceed onward.
He is a Blue Warrior from the Bluegrad city in Siberia (the same which appeared in the short story of Hyōga, Nastassja of the Ice Lands Chapter (氷の国のナターシャ編, Kōri no Kuni no Natāsha Hen) contained in Kurumada's original Saint Seiya manga, tankōbon No.
